CAPTCHA is used to distinguish humans from bots in online banking security. Which option best describes CAPTCHA's role?

• A. CAPTCHA
• B. Password reset questions
• C. Biometric login
• D. Email verification

Answer: (A)

CAPTCHA is a test designed to tell humans apart from automated programs. In online banking, it acts as a gate that a human must pass before proceeding, making it much harder for bots to perform automated login attempts or other scripted abuses. This distinguishes legitimate human users from automated scripts that could try to guess passwords or flood the system, adding a practical barrier against fraud. The other options serve different security roles—password reset questions are for recovering access, biometric login uses physical traits for authentication, and email verification confirms control of an email address—none of which specifically target the human-versus-bot distinction that CAPTCHA provides.
